The 'unread' status of a message is a flag held on the IMAP server.  I
can set a message as unread in Thunderbird, and that mail will be bold
the next time I open a copy of Evolution.  Conversely, if I read some
mail in Thunderbird or webmail, those messages will not be bold when I
next use Evolution (or anything else) - even though they are new to
Evolution.

Evolution knows which messages to download because it holds a list of
the message numbers that it has already got - it queries the imap server
for the list of messages and their status, then downloads the headers &
flags for those it doesn't already have.

No doubt it could filter messages that are new to that instance of Evo -
but it becomes very messy.  

It may well be that the filtering in Thunderbird is not as extensive as
in Evo, and running a filter multiple times on a message is no problem.
But if you have an Evo filter that is scoring a message, then running
the filters multiple times will not have the correct result.
